wonderful place! just enough space for my mother and I during our 5 night stay in Bangkok. Guang and his mother are very sweet and his mother's cooking is spectacular. They even allowed me to do a heavy load of laundry for 100 Baht flat fee. Even more sweet was it was on a rainy day so while I was out, Guang kindly gathered my hanging clothes from the rooftop, folded them, and left them in front of my room to prevent them from getting wet.
The only thing was the 4 floor walk up was a little hard for my 67yo mother to do every day but it shouldn't be an issue for younger folks
